Description
шествп пи в течение 1 часа, 6,2 часа. После 3-X мес цев такой очистки трубопроводов , биообрастани на поверхност х не наблюдалось. Способ обеспечивает очистку от биологических обрастаний трубопроводов, йскщо чает практически полностью биообрастани в системах технического водосиабжетгай. Кроме того, вследствие сильного разбавпени малых объемов хлорной воды, не, загр зн ет водоёмы хлором. и 3 о б р е тек и м у п а Способ очистки от биообрастйшй трубопроводов, включающий промывку тру бопроводов подаваемым под давлением водным раствором с предварительным добавлением в него токсического вещества, о т л и ч а ющ и и с тем, что, с целью улучшени качества очистки, давление водного раствора поддерживают на 1-2 атмг выше давлени транспорттфуемой по трубопроводу воды, причем токсическое вещество добавл ют в количестве 1-1,5 мг/л, а промывку осуществл ют в течение 1-1,5 часа. . Источники информации, прин тые во внимание j при экспертизе 1. Патайт США № 3741.8О7, кл, В 08 В 9/О2 1973. 2.Патент США № 3892588, sn, В 08 В 9/02, 1975.procession pi for 1 hour, 6.2 hours. After 3-X months of this cleaning of pipelines, no biofouling on the surfaces was observed. The method provides for the purification of biological fouling of pipelines, and it is found almost entirely of biofouling in the systems of technical water biabzheggai. In addition, due to the strong dilution of small volumes of chlorine water, non-contaminated water bodies are chlorine. and 3 of a batch of tech and m a p a Method of cleaning bioprotective pipelines, including flushing pipelines with an aqueous solution supplied under pressure with the preliminary addition of a toxic substance into it, so that In order to improve the quality of cleaning, the pressure of the aqueous solution is maintained at 1-2 atmg above the pressure of water transported through the pipeline, the toxic substance is added in an amount of 1-1.5 mg / l, and the washing is carried out for 1-1.5 hours. . Sources of information taken into account j in the examination 1. US Pat. No. 3,741.8O7, CL, B 08 B 9 / O2 1973. 2. US Patent No. 3892588, sn, B 08 B 9/02, 1975.
